Josh and Cleo's family vacation is canceled for the millionth time when their father stops on the way out of his museum and finds a mummy buried there. There's a legend of a curse for anyone who digs it up, but only Josh believes it. They help research the Ring of Eternity and the Elixer of Life that were supposed to be found with the remains of Mina the Egyptian queen. But when they go to pick up some pictures and find both, they then find that the mummy appears to have come to life. Also, things get even more complicated when their house is ransacked by someone else who wants the power for their own.
